In addition, the air conditioner 100 may include the control device 300.

According to an embodiment, the input unit 360 receives, from a user, data on operation of the air conditioner 200, for example, operation setting, an operation mode, a temperature, air volume, a wind direction, and the like, and provides the processor 310 with the received data. In this configuration, the input unit 360 may include a physical manipulation member such as a switch or button, or an electrical manipulation member such as a touch key, a touch pad, or a touch screen.

For example, the input unit 360 may receive data on the operating mode (e.g., a rapid mode, a comfortable mode, a human body adaptation mode, and the like, described below) from a user and provide the processor 310 with the received data. In addition, the processor 310 may drive the air conditioner 200 in the operation mode based on the user input data.

According to an embodiment, the air volume controller 330 may control a discharger to control an amount of air discharged. For example, the air volume controller 330 may control the amount of air discharged through the discharger by adjusting a number of rotations of the blower fan based on the control signal provided by the processor 310.

According to one embodiment, the wind direction controller 340 may control the direction of air discharged by the discharger by adjusting an angle of at least one of the first vane to the fourth vane 210, 220, 230, and 240. For example, the wind direction controller 340 adjusts the rotation angle of the at least one of the first vane to the fourth vane 210, 220, 230, and 240 based on the control signal provided by the processor 310 to control the direction of the discharged air. For example, when the occupant is detected by a motion sensing sensor 260 described below, the wind direction controller 340 may adjust the angle of the at least one of the first vane to the fourth vane 210, 220, 230, and 240 to face the user (e.g., the occupant) under the control of the processor 310.

According to one embodiment, the sensor unit 320 may include a temperature measurement sensor 321 and a motion sensing sensor 260. The temperature measurement sensor 321 includes at least one temperature measurement sensor to measure a temperature and the motion sensing sensor 260 includes at least one motion sensing sensor to detect movement of the object.

According to an embodiment, the temperature measurement sensor 321 may include a plurality of temperature measurement sensors. In addition, the temperature measurement sensor 321 may detect a temperature of the air discharged by the air conditioner 200, a temperature of the air suctioned into the air conditioner 200, an indoor space temperature, a temperature of a refrigerant-suctioning pipe, and a temperature of refrigerant-discharging pipe, and the like, using the temperature measurement sensors, and may provide the processor 310 with the detected result. The temperature measurement sensor 321 may include an infrared camera to measure a temperature.

According to an embodiment, the motion sensing sensor 260 may detect a user (e.g., an occupant) in an indoor space where the air conditioner 200 is disposed. The motion sensing sensor 260 may be disposed on an outer surface of the air conditioner 200 and may be rotatable. The motion sensing sensor 260 may detect a user's movement in the indoor space where the air conditioner 200 is disposed and transmit, to the processor 310, a signal related to the detection degree. Subsequently, the processor 310 may identify whether the user is currently drowsing.

The motion sensing sensor 260 may scan the indoor space by being rotated under the control of the processor 310 and may detect the user (e.g., the occupant) in the indoor space. The motion sensing sensor 260 may detect the user with various methods. For example, the motion sensing sensor 260 may detect the user with infrared rays. In addition, the motion sensing sensor 260 may detect the user using a radiant heat emitted from the user and may detect the user using a camera. The motion sensing sensor 260 may include a vision sensor. In addition, the motion sensing sensor 260 may detect the user using various methods for identifying the user.

The detection operation of the motion sensing sensor 260 may be performed every preset detection period (e.g., 10 seconds) and the motion sensing sensor 260 may provide the processor 310 with the user (e.g., occupant) detection information.

According to an embodiment, the processor 310 may obtain an activity amount of the occupant based on the position of the occupant detected by the motion sensing sensor 260. In addition, the processor 310 may include at least one circuit (or a processor) to control a temperature of the air conditioner 100 using a timer 311 for a preset time period based on the obtained result. The activity amount is a parameter indicating movement degree of an occupant and may be understood as a movement distance of the occupant. Alternatively, the activity amount may be understood as a parameter proportional to the moving distance of the occupant. The processor 310 may identify changes in occupant's position based on the occupant's positions detected every detection time period and may obtain the activity amount of the occupant based on the change in the occupant's positions. For example, the processor 310 may identify the position of the occupant detected by the motion sensing sensor 260 and obtain the activity amount of the occupant based on the change in the occupant's position during a reference period. The processor 310 may identify whether the occupant is currently drowsing based on the obtained result. The processor 310 may control the at least one sensor of the motion sensing sensor 260 to periodically detect the movement of a user's body part (e.g., the head). In addition, the processor 310 may identify whether the user is currently drowsing based on the detection of the movement of the user's body part (e.g., the head).

The processor 310 may detect the indoor environment and operate the air conditioner 200 in a concentration enhancing mode according to a method described below, or only when an instruction regarding the concentration enhancing mode is received from the user, the processor 310 may operate the air conditioner 200 in the concentration enhancing mode. In addition, the processor 310 may operate the air conditioner 200 in a mode (e.g., concentration enhancing mode) selected from various modes (e.g., a concentration enhancing mode, a sleep mode, a refresh mode, and the like).

The processor 310 may measure a temperature change rate for each space based on the temperature change of each space measured by the temperature measurement sensor unit 321. The processor 310 may measure the temperature change rate in a constant time period unit, for example, an hour unit. The processor 310 may identify space information based on the temperature change rate measured by the temperature measurement sensor unit 321. In this case, the processor 310 may control the storage unit 370 to store the space information based on the temperature change rate in advance and detect space information identical to the identified space information of the stored space information. In this case, the space information may include information on an open window, a closed wall, the living room having a large space, and the like.

The at least one processor 310 may control the wind direction controller 340 to automatically swing the at least one vane for a predetermined first sub-time period (e.g., 20 minutes) of the first time period (e.g., between 0 minutes and 60 minutes of 5 hours).

FIG. 6 is a flowchart showing an example process of controlling an air conditioner.

Hereinafter, a process of controlling the air conditioner according to another embodiment of the present disclosure is described in detail with reference to FIG. 6.

According to an embodiment, at least one processor 310 may determine whether an instruction for activating a concentration enhancing mode is input from a user based on a signal received from a remote control device 270 (S610). For example, when the user operates the air conditioner 200 in the concentration enhancing mode, the user may input an operation in the concentration enhancing mode using a button 271 of the remote control device 270. The remote control device 270 transmits, to the air conditioner 200, a signal including an instruction input by pressing the button 271 and the air conditioner 200 may receive the signal including the instruction using the communicator 350. The air conditioner 200 may determine that the user has selected the concentration enhancing mode based on the received signal. The signal may include information on total operation time period for which the air conditioner 200 is operated and the total operation time period may be set by the user.

According to an embodiment, the at least one processor 310 may activate a concentration enhancing mode and activate a vision camera (S612). The at least one processor 310 may operate the air conditioner 200 in the concentration enhancing mode based on the received signal and activate the vision camera of the motion sensing sensor 260.

According to an embodiment, the at least one processor 310 may identify a user (S614). The at least one processor 310 may control at least one of an infrared sensor of the temperature measurement sensor 321 and at least one motion sensing sensor of the motion sensing sensor 260 to identify a user's current position.

According to an embodiment, the at least one processor 310 may identify whether the user is currently drowsing (S616). The at least one processor 310 may control the motion sensing sensor 260 to determine whether the user's body portion (e.g., the head) periodically nods. For example, if the motion sensing sensor 260 determines that that the user's body portion (e.g., the head) periodically nods, the at least one processor 310 may identify that the user is currently drowsing. For example, if the motion sensing sensor 260 determines that the user's body portion (e.g., the head) is not periodically nodding, the at least one processor 310 may identify that the user is not drowsing currently.

According to an embodiment, the at least one processor 310 may control at least one of a wind direction determined based on the adjustment of the vane angle, a temperature, or air volume of the air conditioner in a predetermined time period unit (S618). If the user is not identified by the at least one processor 310 at S614 or the at least one processor identifies that the user is not drowsing at S616, the at least one processor 310 may control at least one of an angle of each of at least one among the vane 210, 220, 230, and 240 adjusted by the wind direction controller 240, the temperature set on the air conditioner 200, and the air volume controlled by the air volume controller 330 in the predetermined time period unit. The at least one processor 310 may analyze information on the total operation time period included in the received signal and divide the total operation time period (e.g., 5 hours) into a plurality of time periods (e.g., a first time period of 0 minutes to 60 minutes, a second time period of 60 minutes to 120 minutes, a third time period of 120 minutes to 180 minutes, a fourth time period of 180 minutes to 240 minutes, and a fifth time period of 240 minutes to 300 minutes). In addition, the at least one processor 310 may control the at least one of the vane angle, the temperature set on the air conditioner, and the volume of air flowing toward the object in each time period (e.g., 1 hour) among the divided time periods to differ from the at least one of the vane angle, the temperature set on the air conditioner, and the volume of air flowing toward the object in the previous time period of the each time period.

According to an embodiment, the at least one processor 310 may control at least one of the wind direction determined through the adjustment of the vane angle, the temperature, or the air volume of the air conditioner in a predetermined time period unit based on the user's current position. (S620). When the processor 310 identifies that the user is drowsing at S616, the at least one processor 310 may control the wind direction controller 340 to adjust angles of the at least one vane 210, 220, 230, and 240 and face the at least one vane 21, 220, 230, and 240 toward the user. In addition, the at least one processor 310 may adjust the temperature set on the air conditioner 200 and control the air volume controller 330 to adjust the air volume. The at least one processor 310 may perform the adjustment in the predetermined time period unit. The at least one processor 310 may divide the total operation time period (e.g., 5 hours) into a plurality of time periods (e.g., the first time period of 0 minutes to 60 minutes, the second time period of 60 minutes to 120 minutes, the third time period of 120 minutes to 180 minutes, the fourth time period of 180 minutes to 240 minutes, and the fifth time period of 240 minutes to 300 minutes). In addition, the at least one processor 310 may control the at least one of the angle of each vane, the temperature set on the air conditioner, and the volume of air flowing toward the object in each period (e.g., 1 hour) among the divided time periods to differ from the at least one of the angle of each vane, the temperature set on the air conditioner, and the volume of air flowing toward the object in the previous time period of the each time period. The at least one processor 310 may adjust the angle of each vane, the temperature set on the air conditioner, and the air volume based on the current position of the object.

FIG. 7 is a flowchart showing an example process of controlling an air conditioner.

Hereinafter, the process of controlling the air conditioner according to another embodiment of the present disclosure is described in detail with reference to FIG. 7.

According to an embodiment, at least one processor 310 may activate a concentration enhancing mode (S710). The at least one processor 310 may receive, from a remote control device 270, a signal including an instruction for the concentration enhancing mode based on the concentration enhancing mode input using the button 271 of the remote control device 270. The signal may include information on the total operation time period for which the air conditioner 200 operates, and the total operation time may be set by a user. For example, when the user wants to operate the air conditioner 200 in the concentration enhancing mode for a certain time period (e.g., 5 hours), the signal may include information on the total operation time period (e.g., 5 hours) set by the user.

According to an embodiment, the at least one processor 310 may determine whether the operation time period of the air conditioner corresponds to a first period or a fifth period (S712). The at least one processor 310 may determine whether a time period during which the air conditioner 200 is operating in the concentration enhancing mode corresponds to the first period (e.g., 0 to 60 minutes) or the fifth period (e.g., 240 to 300 minutes) of the total operation time period (e.g., 5 hours).

According to one embodiment, the at least one processor 310 may set the temperature of the air conditioner to the first temperature (S714). When the at least one processor 310 determines that the operation time period of the air conditioner 200 corresponds to the first period or the fifth period, the at least one processor 310 sets the temperature of the air conditioner 200 to a first temperature (e.g., 27 Celsius degrees). The first temperature may include an initial set temperature. The at least one processor 310 may periodically check the current temperature and determine that the checked current temperature is the same as the first temperature.

According to an embodiment, the at least one processor 310 may determine whether the operation time period of the air conditioner corresponds to the first period (S716). The at least one processor 310 may determine that the operation time period corresponds to the first period (e.g., 0 to 60 minutes) of the total operation time period (e.g., 5 hours) while the air conditioner 200 is operated to reach the first temperature.

According to an embodiment, the at least one processor 310 may automatically swing at least one vane for a predetermined time period (S718). When the at least one processor 310 determines that the operation time period of the air conditioner corresponds to the first period (e.g., 0 minutes to 60 minutes) of the total operation time period (e.g., 5 hours) at S716, the at least one processor 310 may automatically swing at least one vane 210, 220, 230 and 240 of the air conditioner 200 for a predetermined time period (e.g., 20 minutes) to adjust the wind direction of the at least one vane 210, 220, 230, and 240. The automatic swing refers to swinging at least one vane 210, 220, 230, and 240 of the air conditioner 200 from 0° to 90°.

According to one embodiment, the at least one processor 310 may operate the air conditioner in a first mode (S720). The at least one processor 310 automatically swings at least one vane 210, 220, 230, and 240 of the air conditioner 200 for the predetermined time period (e.g., 20 minutes) and control the air conditioner 200 to be operated in the first mode. The first mode is a mode in which the at least one processor 310 controls the air volume controller 330 to adjust the volume of air discharged through the at least one vane 210, 220, 230, and 240 to first air volume (e.g., high air volume). The first mode is a mode in which the at least one processor 310 controls the wind direction controller 340 to move the at least one vane within a first angular range (e.g., within 0° to 30°) for a predetermined second sub-time period (e.g., 60 seconds), and after the predetermined second sub-time period, move the at least one vane within a second angular range (e.g., within 30° to 80°) that is greater than the first angular range for a predetermined third sub-time period (e.g., 60 seconds). In addition, the first mode is a mode in which the at least one processor 310 controls the wind direction controller 340 to automatically swing the at least one vane for a predetermined fourth sub-time period (e.g., 90 seconds) after the predetermined third sub-time period. The at least one processor 310 may repeatedly perform the above operation for a rest time period (e.g., 40 minutes) of the first period (e.g., 0 to 60 minutes) after the predetermined time period (e.g., 20 minutes) in the first mode.

According to an embodiment, the at least one processor 310 may determine whether an operation time period of the air conditioner corresponds to the first period (S722). The at least one processor 310 periodically checks the operation time period of the air conditioner 200 while the air conditioner 200 is operating in the first mode to determine whether the operation time period of the air conditioner 200 corresponds to the first period (e.g., 0 minutes to 60 minutes).

According to one embodiment, the at least one processor 310 may determine whether the operation time period thereof corresponds to the fifth period (S724). The at least one processor 310 may periodically check the operation time period of the air conditioner 200 while the air conditioner 200 is operating in the first mode. In addition, when the at least one processor 310 determines that the operation time period of the air conditioner 200 does not correspond to the first period, the at least one processor 310 may determine whether the operation time period of the air conditioner 200 corresponds to the fifth period (e.g., 240 to 300 minutes).

According to one embodiment, the at least one processor 310 may determine whether the operation time period of the air conditioner 200 corresponds to the third period (S726). When the at least one processor 310 determines that the operation time period of the air conditioner 200 does not correspond to the fifth period, the at least one processor 310 may determine whether the operation time period of the air conditioner 200 exceeds a predetermined total operation time period (e.g., 5 hours) (S736). When the at least one processor 310 determines that the operation time period of the air conditioner 200 does not exceed the total operation time period, the process returns back to S712, and the at least one processor 310 may determine that the operation time period of the air conditioner corresponds to the fifth period (e.g., 240 to 300 minutes) (S712). When the at least one processor 310 determines that the operation time period of the air conditioner 200 does not correspond to the fifth period, the at least one processor 310 may determine whether the operation time period of the air conditioner 200 corresponds to the third period (e.g., 120 to 180 minutes) (S726).

According to one embodiment, the at least one processor 310 may operate the air conditioner at a second temperature (S728). When the at least one processor 310 determines that the operation time period of the air conditioner 200 corresponds to the third period, the at least one processor 310 sets the temperature of the air conditioner 200 to the second temperature (e.g., 28 Celsius degrees). The second temperature (e.g., 28 Celsius degrees) may be a temperature higher than the first temperature (e.g., 27 Celsius degrees) by a preset temperature (e.g., 1 Celsius degree). The at least one processor 310 may periodically check the current temperature and determine that the checked current temperature is the same as the second temperature.

According to one embodiment, the at least one processor 310 may operate the air conditioner in a second mode and a third mode (S730). The at least one processor 310 may control the air conditioner 200 to sequentially and repeatedly operate the air conditioner 200 in the second mode and the third mode. The second mode is a mode in which the at least one processor 310 operates the air conditioner to adjust the first temperature (e.g., 27 Celsius degrees) in the first mode to a second temperature (e.g., 28 Celsius degrees) that is greater than the first temperature by the predetermined temperature (e.g., 1 Celsius degree) and the at least one processor 310 controls the air volume controller 330 to adjust the air volume to the second air volume (e.g., low air volume) that is less than the first air volume (e.g., high air volume). The third mode is a mode in which the at least one processor 310 controls the air volume controller 330 to adjust the second air volume in the second mode to the first air volume.

For example, the second mode is a mode in which the at least one processor 310 controls the air volume controller 330 to adjust the volume of air discharged through the at least one vane 210, 220, 230, and 240 to the second air volume (e.g., low air volume). The second mode is a mode in which the at least one processor 310 controls the wind direction controller 340 to move the at least one vane within a first angular range (e.g., within 0° to 30°) for a predetermined second sub-time period (e.g., 60 seconds), and after the predetermined second sub-time period, to move the at least one vane within a second angular range (e.g., within 30° to 80°) that is greater than the first angular range for the predetermined third sub-time period (e.g., 60 minutes). The second mode is a mode in which, after the predetermined third sub-time period, the at least one processor 310 controls the wind direction controller 340 to automatically swing the at least one vane for a predetermined fourth sub-time period (e.g., 90 seconds).

In addition, the third mode is a mode in which the at least one processor 310 controls the air volume controller 330 to adjust the air volume discharged through the at least one vane 210, 220, 230, and 240 to the first air volume (e.g., high air volume). In addition, the third mode is a mode in which the at least one processor 310 controls the wind direction controller 340 to move the at least one vane within the first angular range (e.g., within 0°˜30°) for the predetermined second sub-time period (e.g., 60 seconds), and after the predetermined second sub-time period, the at least one vane moves within a second angular range (e.g., within 30°˜80°) that is greater than the first angular range for a predetermined third sub-time period (e.g., 60 seconds). In addition, after the predetermined third sub-time period, the third mode is a mode in which the at least one processor 310 controls the wind direction controller 340 to automatically swing the at least one vane for the predetermined fourth sub-time period (e.g., 90 seconds).

The at least one processor 310 may control the air conditioner 200 to be operated repeatedly and alternately in the second mode and the third mode in the second period (e.g., 60 to 120 minutes).

According to an embodiment, the at least one processor 310 may determine whether the operation time period of the air conditioner corresponds to the second period (S732). The at least one processor 310 periodically checks the operation time period of the air conditioner 200 while the air conditioner 200 is repeatedly operated in the second mode and the third mode to determine whether the operation time period of the air conditioner 200 corresponds to the second period (e.g., 60 to 120 minutes).

According to one embodiment, the at least one processor 310 may determine whether the operation time period of the air conditioner corresponds to the fourth period (S734). The at least one processor 310 may periodically check the operation time period of the air conditioner 200 while the air conditioner 200 is repeatedly operated in the second mode and the third mode. In addition, when the at least one processor 310 determines that the operation time period of the air conditioner 200 does not correspond to the second period (e.g., 60 minutes to 120 minutes), the at least one processor 310 may determine that the operation time period of the air conditioner 200 corresponds to the fourth period (e.g., 180 to 240 minutes).

According to one embodiment, the at least one processor 310 may determine whether the operation time period of the air conditioner is greater than the total operation time period (S736). When the at least one processor 310 determines that the operation time period of the air conditioner 200 does not correspond to the fourth period, the at least one processor 310 may determine whether the operation time period of the air conditioner 200 exceeds the predetermined total operation time period (e.g., 5 hours) (S736). When the at least one processor 310 determines that the operation time period of the air conditioner 200 does not exceed the total operation time period, the process returns back to S712, and the at least one processor 310 may determine whether the operation time period of the air conditioner corresponds to the fifth period (e.g., 240 to 300 minutes) (S712). When the at least one processor 310 determines that the operation time period of the air conditioner 200 does not correspond to the fifth period, the at least one processor 310 may determine whether the operation time period of the air conditioner 200 corresponds to the third period (e.g., 120 to 180 minutes) (S726).

According to one embodiment, the at least one processor 310 may operate the air conditioner at a third temperature (S738). When the at least one processor 310 determines that the operation time period of the air conditioner 200 does not correspond to the third period, the at least one processor 310 sets the temperature of the air conditioner 200 to the third temperature (e.g., 29 Celsius degrees). The third temperature (e.g., 29 Celsius degrees) may be a temperature higher than the second temperature (e.g., 28 Celsius degrees) by a preset temperature (e.g., 1 Celsius degree). The at least one processor 310 may periodically check the current temperature and determine that the checked current temperature is the same as the third temperature.

According to one embodiment, the at least one processor 310 may operate the air conditioner in the first mode (S740). The first mode at S740 may have the same set time and angular range of each vane as the first mode at S720. Alternatively, the first mode at S740 may have different set time or angular range of at least one vane from the set time or the angular range of the as least one vane in the first mode at S720.

According to an embodiment, the at least one processor 310 may determine whether the operation time period of the air conditioner 200 corresponds to the third period (S742). The at least one processor 310 periodically checks the operation time period of the air conditioner 200 while the air conditioner 200 is operated in the first mode to determine whether the operation time period of the air conditioner 200 corresponds to the third period (e.g., 120 minutes to 180 minutes).

According to an embodiment, the at least one processor 310 may deactivate a concentration enhancing mode (S744). When the at least one processor 310 determines that the operation time period of the air conditioner 200 does not correspond to the third period, at least one processor 310 may determine that the operation time period of the air conditioner 200 exceeds the total operation time period (e.g., 5 hours) of the air conditioner 200. When the at least one processor 310 determines that the operation time period of the air conditioner 200 exceeds the total operation time period (e.g., 5 hours), the at least one processor 310 may deactivate the concentration enhancing mode. The at least one processor 310 may deactivate the concentration enhancing mode that is activated according to user's requests. After the concentration enhancing mode is deactivated, the at least one processor 310 may terminate the operation of the air conditioner 200 or control the air conditioner through cooling and heating.

At least one of the time period or the angular ranges described above is only an example, and may be variably changed or adjusted to other times or other angular ranges.

FIG. 8 is a flowchart showing an example operation process of an air conditioner in a first mode.

Hereinafter, an operation process of the air conditioner in the first mode according to an embodiment of the present disclosure is described in detail with reference to FIG. 8 as follows. The processes of FIG. 8 may be performed in at least one of the processes (e.g., S720, S730, and S740) of FIG. 7.

According to an embodiment, the at least one processor 310 may operate the at least one vane within a first angular range for a first time period (S810). The at least one processor 310 may control the at least one vane 210, 220, 230, and 240 of the air conditioner 200 to move within a first angular range (e.g., within 0° to 30°) for a predetermined first sub-time period (e.g., 60 seconds) to discharge indirect wind. The first angular range (e.g., within 0° to 30°) may be an angular range in which the wind does not directly flows toward an occupant (or a user), but flows toward a periphery of the occupant (e.g., above the head or in a direction not toward the occupant). The at least one processor 310 may control the at least one sensor (e.g., the motion sensing sensor) disposed at an outer portion of the air conditioner 200 to determine presence or absence of an occupant and the position of the occupant. The at least one processor 310 may control the wind direction controller 340 to gradually increase the angle of the at least one vane from 0° to 30° during the predetermined sub-time period (e.g., 60 seconds) and control the wind direction controller 340 to gradually decrease the angle of the at least one vane from 30° to 0°. The at least one processor 310 may control the wind direction controller 340 to move at least one vane within the first angular range during the predetermined time period (e.g., 60 seconds) and control the air volume controller 330 to adjust the air volume to low air volume, medium air volume, or high air volume.

According to one embodiment, the at least one processor 310 may operate the at least one vane within a second angular range for a second time period (S810). The at least one processor 310 may control the at least one vane 210, 220, 230, and 240 of the air conditioner 200 to move within the second angular range (e.g., within 30° to 90°) for the predetermined second sub-time period (e.g., 60 seconds) to discharge direct wind. The first angular range (e.g., within 30° to 90°) may be an angular range in which the wind directly flows toward the occupant (or the user). The at least one processor 310 may control the wind direction controller 340 to gradually increase the angle of the at least one vane from 30° to 90° during the predetermined time period (e.g., 60 seconds) and control the wind direction controller 340 to gradually decrease the angle of the at least one vane from 90° to 30°. The at least one processor 310 may control the wind direction controller 340 to move the at least one vane within the second angular range for the predetermined time period (e.g., 60 seconds) and control the air volume controller 330 to adjust the air volume to low air volume, mediate air volume, or high air volume.

According to one embodiment, the at least one processor 310 may automatically swing the at least one vane to operate for a third time period (S814). The at least one processor 310 may automatically swing the at least one vane 210, 220, 230, and 240 of the air conditioner 200 during the third time period (e.g., 90 seconds) to adjust the angle of the at least one vane 210, 220, 230, and 240. The automatic swing refers to swinging of at least one vane 210, 220, 230, and 240 of the air conditioner 200 from 0° to 90°. According to an embodiment, the at least one processor 310 may repeatedly perform the steps (e.g., S810, S812, and S814) in a predetermined time period unit (e.g., 1 hour unit).

FIG. 9 is an exemplary view showing example direct wind and indirect wind discharged based on a user's position.

Referring to FIG. 9, according to an embodiment of the present disclosure, when a user is located at a first position 910, direct winds 911 and 912 are discharged from a first vane 20 among at least one vane 210, 220, 230, and 240 of the air conditioner 200 and directly flow toward the user. Indirect wind 913 is discharged from the first vane 210 among the at least one vane 210, 220, 230, and 240 of the air conditioner 200 and directly flows toward the user.

According to an embodiment, when the user is located at a second position 920, direct wind 913 is discharged from the first vane 210 among the at least one vane 210, 220, 230, and 240 of the air conditioner 200 and directly flows toward the user. The indirect winds 911 and 912 are discharged from the first vane 210 among the at least one vane 210, 220, 230, and 240 of the air conditioner 200 and directly flow toward the user.

The at least one processor 310 controls the wind direction controller 340 to face the at least one vane 210, 220, 230, and 240 of the air conditioner 200 toward the user. Based on the above operations, the wind direction controller 340 may directly face the wind discharged from the at least one vane toward the user (e.g., discharge the direct wind) or indirectly face the wind discharged from the at least one vane toward the user (e.g., discharge the indirect wind).

At least one processor 310 may control a least one motion sensing sensor disposed at the outer portion of the air conditioner 200 to identify a position of the user and determine whether a body portion (e.g., the head) of the identified user is periodically moving. For example, when the user's body portion (e.g., the head) is periodically moving, the at least one processor 310 may identify that the user is currently drowsing. When the at least one processor 310 identifies that the user is currently drowsing, the at least one processor 310 may automatically activate a concentration enhancing mode. According to an embodiment, at least one of the angle of each of vanes, a temperature set on the air conditioner, and volume of air flowing toward the subject may be changed compared to a predetermined value based on the position of the user, a distance between the user and the air conditioner, a direction of the vane of the air conditioner.

Referring to FIGS. 10, 11A, and 11B, at least one processor 310 may control a communicator 350 to receive a signal from a remote control device 270 and identify total operation time period information included in the received signal. The total operation time period is a user set time period for which the air conditioner 200 is operated in a concentration enhancing mode. The at least one processor 310 may divide the total operation time period (e.g., 5 hours) into a plurality of time periods 1010, 1020, 1030, 1040, and 1050 and control at least one of the angle of each vane, the temperature set on the air conditioner 200, and volume of air flowing toward the user in each time period unit (e.g., 1 hour unit) among the divided time periods. The at least one processor 310 may control the at least one of the angle of each of vanes, the temperature, and the air volume in each time period to differ from the at least one of the angle of each of vanes, the temperature, and the air volume in a previous time period of the each time period and operate the air conditioner 200 based on the controlled configurations.

For example, during a first time period 1010 of the total operation time period (e.g., 5 hours), the at least one processor 310 may control the air conditioner 200 to be operated in the concentration enhancing mode like as a first pattern 1011 in which the at least one processor 310 adjusts the air volume to high wind volume, a temperature to a set temperature (T0), the angle of the vane from 20° to 80°. For a second time period 1020 of the total operation time period (e.g., 5 hours), the at least one processor 310 may operate the air conditioner 200 like as a second pattern 1021 in which the at least one processor 310 adjusts the air volume of the air conditioner 200 to high air volume and medium air volume, the temperature to a set temperature (T0+1), and the angle of the vane from 20° to 80°. For a third time period 1030 of the total operation time period (e.g., 5 hours), the at least one processor 310 may operate the air conditioner 200 like as a third pattern 1031 in which the at least one processor 310 adjusts the air volume of the air conditioner 200 to high air volume, the temperature to a set temperature (T0+2), and the angle of the vane from 20° to 80°. For a fourth time period 1040 of the total operation time period (e.g., 5 hours), the at least one processor 310 may operate the air conditioner 200 like as a fourth pattern 1041 in which the at least one processor 310 adjusts the air volume of the air conditioner 200 to high air volume and medium air volume, the temperature to a set temperature (T0+1), and the angle of the vane from 20° to 80°. The operation pattern of the air conditioner 200 for the second time period 1020 may be identical to the operation pattern of the air conditioner 200 for the fourth time period 1040. In addition, for a fifth time period 1050 of the total operation time period (e.g., 5 hours), the at least one processor 310 may operate the air conditioner 200 like as a fifth pattern 1051 in which the at least one processor 310 adjusts the air volume of the air conditioner 200 to high air volume, the temperature to a set temperature (T0), and the angle of the vane from 20° to 80°.

Referring to FIGS. 11A and 11B, an angle of each of vanes may be variously adjusted. For example, when wind discharged from the air conditioner 200 is indirect wind, the angle of the at least one vane may be gradually adjusted from a first angle 1110 to a second angle 1120. In addition, when the wind discharged from the air conditioner 200 is direct wind, the angle of the at least one vane may be gradually adjusted to a third angle 1130, a fourth angle 1140, a fifth angle 1150, a sixth angle 1160, and a seventh angle 1170. The angle of the at least one vane may be adjusted to the third angle 1130 in a reverse sequence after the seventh angle. At least one of the first angle, the second angle, the third angle, the fourth angle, the fifth angle, the sixth angle, or the seventh angle may be adjusted to have a different angle value.

FIG. 12A is an exemplary view showing vane angles in each mode and operation time periods at each angle adjusted to have different values. FIG. 12B is an exemplary view showing an example result of adjusting angles in each mode and operation time periods at each angle to have different values.

Referring to FIGS. 12A and 12B, a first experiment 1210 is an example in which an air conditioner is operated at 20° of angle of at least one vane for 60 seconds, at 45° of angle of at least one vane for 60 seconds, and from 40° to 80° of angle of the at least one vane for 90 seconds. A second experiment 1220 is an example in which the air conditioner is operated at 20° of angle of at least one vane for 60 seconds, at 45° of angle of the at least one vane for 60 seconds, and at 40° to 80° of angle of the at least one vane for 120 seconds.

A third experiment 1230 is an example in which the air conditioner is operated at 20° of angle of at least one vane for 60 seconds, at 45° of angle of the at least one vane for 60 seconds, and from 40° to 80° of angle of the at least one vane for 90 seconds. A fourth experiment 1240 is an example in which the air conditioner is operated at 20° of angle of at least one vane for 60 seconds, at 40° of angle of the at least one vane for 60 seconds, and from 20° to 80° of angle of the at least one vane for 90 seconds. According to the experiments executed under the above conditions, the higher the stimulus is, the higher the concentration is in the fourth experiment as shown in FIG. 12B.

FIG. 13 is an exemplary view showing an example result of measuring brainwave before and after executing a concentration enhancing mode.

Referring to FIG. 13, an alpha level and a beta level are significantly increased after executing the concentration enhancing mode than before executing the concentration enhancing mode. The alpha level refers to a person's comfort and the beta level refers to a person's concentration and awakening. The higher the alpha level is, the higher the comfort index is, and the higher the beta level is, the higher the concentration or awakening is. For example, the alpha wave ratio before executing the concentration enhancing mode was 12.4%, but the alpha wave ratio after executing the concentration enhancing mode was increased to 15%, indicating that the user's comfort was improved. In addition, the beta wave ratio before executing the concentration enhancing mode was 17.6%, but the beta wave ratio after executing the concentration enhancing mode was increased to 24.1%, indicating that the user's concentration and awakening were improved.
